The present invention proposes a protocol based on multiple transmission and contention rounds that schedules several transmission rounds after the contention phase is completed. The multiple transmission rounds reduce the sending of control packets and substantially increase the cross traffic on the uplink to the AP. The supporting analytical expressions for determining the traffic carried of the proposed protocol demonstrate through simulation that about 94% of the ideal throughput of available throughput can be achieved by using as few as four transmission rounds during the transmission period.

The present invention discloses the discovery of the genes that direct the biosynthetic pathway of leupeptin, a potent protease inhibitor of the type of small peptide aldehyde (SPA). The prediction of genes that direct the biosynthesis of leupeptin was performed by EvoMining, a bioinformatic pipeline for genome mining of natural products that is based on evolutionary parameters, and was confirmed by molecular biology techniques such as insertional mutagenesis and comparison of metabolomic profiles between wild strains (producers of leupeptin) and mutant strains (non-producers of leupeptin). The leupeptin-coding biosynthetic genes contained in the isolated cluster according to the present invention were heterologously expressed in E. coli, thus achieving the production of leupeptin.

The present invention describes a portable thermocycler for RT-qPCR (dubbed HybOT Cycler) that integrates thermal control, illumination, and fluorescence detection into a highly integrated hybrid module, simplifying its assembly. The HybOT Cycler is wirelessly controlled from an application installed in a tablet. We characterized its thermal performance and fluorescence sensitivity and found it to behave similarly to benchtop thermocyclers. We developed a bubble-free microfluidic device that can be easily replicated from an acrylic mold to run the PCR assays. Degassing the PCR chambers for 3 min at 350 KPa with a portable vacuum pump prevented any bubbles during the assay. Both the instrument and the microfluidic mold are fabricated with digital fabrication tools and off-the-shelf electronics. Concentrations as low as 103 copies/µL of the SARS-CoV-2 N1 gene were detected. We then used our platform to screen individuals infected with the virus, reaching a sensitivity of 95% and specificity of 100%. Our portable platform can assist in diagnosing of SARS-CoV-2 and other pathogens, and its simple configuration and assembly can lead to quick adoption by labs around the world.

Broadband channel emulation is currently carried out by channel executions based on dispersion functions dictated by communication standards with the purpose of performing tests and validating new communication schemes. However, the channel models available in the prior art consider only the simulation of channel which has stationary statistics and wherein the dispersion is separable, allowing only unrealistic channel simulations. The present invention describes a method and apparatus for emulating doubly selective scene channels, wherein the simulation and emulation has a randomly long duration for a stationary or non-stationary channel, with non-separable dispersion. The above is achieved by combining the techniques of channel orthogonalisation, decomposition of the correlation tensor in the Doppler variable in frequency-dependent correlation matrices, followed by a matrix factorisation of each of the aforementioned matrices and, finally, the use of the window method in order to be able to generate randomly long executions. This makes it possible to concatenate channel executions coming from same or different NSDFs, thus reproducing stationary or non-stationary channels, respectively.

The invention describes a method and apparatus for generating single-hand multi-h CPM signal waveforms, in which all the signal-generation parameters can be reconfigured. This apparatus amply beats the transmitters disclosed in the prior art, such as that based on memories and that based on integration, in terms of hardware resource consumption, while also having reliable performance in terms of SQNR for any of the implementations. The described generation methodology is divided into two steps: one associated with the moving average term and one with the autoregressive term. The present invention proposes a generation of the autoregressive term based on digital signal processing and memory elements. The proposed method for generating CPM signals is carried out by DSP and memory elements in order to improve the cases in which the transmitter based only on DSP has poor performance in terms of SQNR. When the symbols to be transmitted are multiplied by the one or more modulating indices, the product is sent to an interpolation filter, which responds to the pulse with the PSR of the CPM scheme. On the other hand, in the autoregressive section, the symbols to be transmitted are multiplied by the numerator of the one or more modulation indices in order to generate a change in the current position of the phase. The sum of the outputs of the autoregressive term obtained from memory elements and the autoregressive term generated by the interpolation filter is used as an argument for the normalised sine and cosine functions.

In contrast to any existing invention operating under the same conditions, the described apparatus uses a completely novel receiving technique based on the concept of non-linear detection of signals with frequency dispersion. The receiver of this apparatus can achieve a level of performance such that it efficiently exploits the diversity in frequency, together with the band structure of the equivalent channel matrix. The performance achieved in terms of noise immunity is much better than any technique that has been found up to now and also requires a much smaller number of calculations in the receiver.

The invention relates to a method and apparatus for emulating channels having time-selective and arbitrary dispersion scenarios (channels with isotropic and non-isotropic distributions in the angle of arrival or, otherwise, asymmetric and non-asymmetric channels with spectral power densities and which are affected by Doppler shifts). The present invention also allows arbitrarily long channel realisations to be generated for channels having non-stationary statistics, allowing real channels to be emulated. Stationary and non-stationary channels are simulated by concatenating independent sequences and by applying a window to the sequences generated, using a forming filter that enables this type of model to be implemented in time-selective channel emulators by means of hardware. The sequences are channel realisations obtained using any method for generating stochastic processes such as: adding orthogonal functions, adding sine waves/cosine waves, filtering, Fourier transform, etc.

Streptomyces lividans 66, which we have called livipeptin. Using genome mining of natural products, we predicted that SLI0883-5 genes encode an unprecedented biosynthetic system, unusually small (4.6 Kbp), which produces an acylated peptide aldehyde. Because of the chemical characteristics of the predicted compound, we postulated its anti-proteolytic activity, which we confirmed by identifying and purifying this compound through metabolic profiles of HPLC and MS of the mutated strain lacking these three genes and the wild strain. To this objective, we identified the conditions wherein these genes are strongly expressed. The livipeptin was purified and its inhibitory activity on the proteolytic activity of selected proteases was demonstrated in vitro. The design of an expression cassette for its heterologous expression is also described plus its use for heterologous protein production.

The present invention describes the discovery of the genes that direct the biosynthetic pathway of leupeptin, a potent protease inhibitor of the type of small peptide aldehyde (SPA). The prediction of genes that direct the biosynthesis of leupeptin was performed by EvoMining, a bioinformatic pipe for genome data mining of natural products based on evolutionary parameters and was confirmed by molecular biology techniques such as insertional mutagenesis and the comparison of metabolomic profiles between wild strains (producers of leupeptin) and mutants (non producers of leupeptin). Biosynthetic genes of leupeptin were cloned and expressed heterologously in other expression systems of bacterial origin, thus achieving the production of leupeptin. It also describes the design of a cassette for heterologous production of leupeptin and its use for producing leupeptin and variants of it using synthetic biology, and to produce recombinant proteins.

The invention describes the computational automation of baseball, which is supported on a finite state automaton and a formal language for describing any correct play. Using this automaton and this language ensure the mathematically correct modelling and implementation of the algorithms for computer simulation of a baseball game. For algorithmic automation of baseball according to the invention, a formal grammar is defined that translates the rules of the baseball game; by using said grammar, a formal language is generated to describe any possible play during a baseball game. This formal language is read by the corresponding state automaton. Also, a generator of baseball plays creates the plays based on average probability occurrence of each of these plays in games played by humans in professional tournaments. Therefore, plays such as "STRIKES", "FOULS", "HITS", "HOMERUN", including the number of runs, etc., occur according the rules of the game and with the average frequency with which would occur in real life matches.

The present invention describes a new peptide aldehyde produced naturally by Streptomyces lividans 66, which we have called livipeptin. Using genome mining of natural products, we predicted that SLl0883-5 genes encode an unprecedented biosynthetic system, unusually small (4.6 Kbp), which produces an acylated peptide aldehyde. Because of the chemical characteristics of the predicted compound, we postulated its anti-proteolytic activity, which we confirmed by identifying and purifying this compound through metabolic profiles of HPLC and MS of the mutated strain lacking these three genes and the wild strain. To this objective, we identified the conditions wherein these genes are strongly expressed. The livipeptin was purified and its inhibitory activity on the proteolytic activity of selected proteases was demonstrated in vitro. The design of an expression cassette for its heterologous expression is also described plus its use for heterologous protein production.

The present invention relates to methods for identifying bean plants tolerant to drought. This method is based on the molecular and physiological evaluation of plants, which are exposed to water stress. The molecular evaluation is performed by identifying and quantifying the m RNAs of genes accumulated under water stress and the physiological evaluation by measuring the photosynthesis. For the development of the present invention, we took as study model the Pinto Villa bean variety from which various different nucleotide sequences of 44 genes were identified, overexpressing in the bean plants when these are exposed to water stress. Therefore, it represents the value of employing said sequences as molecular markers useful to identify bean plants tolerant to drought. This invention allows assisting the selection of drought tolerant plants with molecular markers and physiological parameters in bean seedlings, without having to wait for the occurrence of the life cycle of the plant, by that reducing the time of identification of drought tolerant plants noticeably.

Abstract. This invention relates to a high-capacity data hiding method for audio signals following the OFDM concept. It is based on changing the phase component of the audio signal via an M-order Phase Shift Keying (MPSK) modulator on selected frequency samples of the audio signal. This approach allows the data hiding capacity and perceptual distortion to be controlled by the number of altered frequency components of the audio signal and the severity of this alteration. The data hiding capacity can be estimated a priori independently of the audio signal features. In addition, due to the relation of the proposed scheme with the traditional use of MPSK modulation, the BER of the encoded data is analytically derived, therefore, it is known in advance, allowing the integration of channel encoders. Results obtained with representative test cases show that the proposed algorithm provides an increase of one order of magnitude in data payload compared with state-of-the-art works.
